Specific format in configuring IPv6 on Yealink IP phones
Scenario 1:
If the IP phone obtains the IPv6 address, the format of the URL to access the web user interface is “ [IPv6 address]”
or “ http(s)://[IPv6 address] ”. For example, if the IPv6 address of your phone is “fe80::204:13ff:fe30:10e”, you can
enter the URL (for example, “[fe80::204:13ff:fe30:10e]” or “http(s)://[fe80::204:13ff:fe30:10e])” in the address bar of
a web browser on your PC to access the web user interface.
Scenario 2:
Yealink IP phones support using FTP, TFTP, HTTP and HTTPS protocols to download configuration files or resource
files. You can use one of these protocols for provisioning.
When provisioning your IP phone to obtain an IPv6 address, the provisioning server should support
IPv6 and the format of the access URL of the provisioning server can be “ tftp://[IPv6 address or domain
name] ”. For example, if the provisioning server address is “2001:250:1801::1”, the access URL of the
provisioning server can be “tftp://[2001:250:1801::1]/”. For more information on provisioning, refer to
